The bypass capacitors should include a 100nF, ceram-
ic surface-mount capacitor between each supply pin
and the ground plane, located as close to the package
as possible. Optionally, place a 10μF tantalum capaci-
tor at the power-supply pins’ point of entry to the PC
board to ensure the integrity of incoming supplies. The
power-supply trace should lead directly from the tanta-
lum capacitor to the V
CC
and V
EE
pins. To minimize
parasitic inductance, keep PC traces short and use sur-
face-mount components.
If input termination resistors and output back-termination
resistors are used, they should be surface-mount types,
and should be placed as close to the IC pins as possible.
V ideo Line Driver
The MAX4310–MAX4315 are well-suited to drive coaxial
transmission lines when the cable is terminated at both
ends, as shown in Figure 5. Cable frequency response
can cause variations in the signal’s flatness.
